-- CURTAIN INDQW INSTALLATION.

Application filed January 14, 1925. Serial No. 2,286.

This invention aims to provide an improved curtain window installation.

In the drawings, which illustrate three preferred embodiments of my invention Figure 1' is an elevation view of the installation, partly broken away to show the elements for securing the frame parts to the curtain; i i

Fig. 2 is an edge view of the installation without the glass and showing the normal flex ofthe frame;

Fig. 3 is a view similar to Fig. 2, showing the installation after the'glass has been inserted;

4-4 of Fig. 1;

Fig. 5 is an enlarged section on the line 5-5 of Fig. 1; I Fig. 6 isa fragmentary view of one end the frames removed to permit changing the glass;

Fig. 7 is a fragmentary view of a portion of the installation showing a second form of tension device;

Fig. 8 is asection on the line. 8-8 of Fig. 7; I

Fig. 9 is an end elevation of the installation with the end of one of the frames removed to show how the glass is placed in theframe; and i I I 1 Fig. 10 is a section similar to Fig. 5, but showing the curtain arranged differently in relation to the glass.

Referring to the drawings, I have shown a curtain window installation which includes a frame having a removable end portion. The frame members of the frame, except the removable 'end, are permanently secured to the curtain fabric and the glass may be removed and replaced simply by removing the removable end portion of one of the frame members, thereby to permit sliding the glass in and out of the fixed part of the frame, in a plane parallel with the frame parts;

Thus I have provided a curtain window installation which is neat, simple, inexpensive and durable, and is very desirable because the glass may be changed any number of times without affecting the means by which the frame members'are secured to the curtain. I

Referring now to the installation shown F ig; 4 is an enlarged sectiononthe line of the installation showing the end of one of.

in Figs. 1 through 6, I have shown a frame of which the greater-part is permanently secured to the curtain fabric 1. This frame comprises a prong-presenting frame art 2 and a prong-receiving and glass-hol ing frame part 5 secured to opposite sides of the curtain 1 by a plurality of prongs 3, which pass through the curtain'and through slots 4 in the frame part 5. After the prongs are clenched against the frame member. 5, the upstanding flange 6, shown in dotted lines in Fig. 4, is bent inwardly and downward- 1y against the prongs '3 to conceal them. I

The inner portion of the glass-holding frame part 5 presents an angle shaped portion 6 which provides a continuous groove for reception of the glass 7, as best shown in Figs. 4, 5 and 9.

The glass-holding frame member is pref erably provided with a removable end portion 8 (Figs. 1 and 6), so that the glass may be slid into and out of the glass-holding frame without removing the rest of the frame parts from the curtain. While the frame parts may be perfectly flat, I have found that the glass can be held more firms0 ly in the frame by initially flexing both frame members, as shown in Fig. 2. Thus when the glass is slid into the groove provided by the glass-holdingframe, the frame is flattened, as shown in Fig. 3, and a tension is exerted upon the glass to prevent it from. rattling in the frame.

' The removable end portion 8 'may be secured in position to keep the glass from sliding out of the frame part'5by a plurality of attachingscrews 9, preferably of the self-piercing type. These screws may be located at the corners of the frame where the flange 6 is cut outto turn the corners of the frame part 5, and they extend through the cloth and thread themselves into indentations in the prong-presenting frame part 2, asshown in Fig. 5.

The frame part 2 is provided with an outwardly extending central beaded portion'lO, which stifl'fens the frame part and also pro vides a recess into which the self-piercing screws 9 may extend (Fig. 5) after threading themselves into the frame part 2.

Vhen theframe parts 2 and 5 are assembled to the curtain and the glass is inserted into place, the curtain. 1, which is gripped between the frame members, extends inwardly so as to provide a cushion between one side of the glass and the frame part 2. Thus any undue pressure exerted upon the glass by the natural tendency of the frame to flex, will be offset by the cushion-.

and described in relation to the first pre-- ferred embodiment of my invention, except that in place of making them initially flexed, I have provided a plurality of pockets 12 in the upper part of the angle-shaped portion 6 for receiving suitable flexible material to press upon the glass 7. The pockets 12 are spaced about the frame part 5 and are preferably curved in cross-section so as to provide a narrow opening between the glass 7 and the inner edges of the frame part 5, as shown in Fig. 8.

The flexible material preferably comprises short ronnd rubber strips 13 which, when forced into the pockets 12, are compressed and exert pressure upon the glass, thereby forming a cushion between the glass 7 and frame 5.

Referring now to Fig. 10, which illustrates a third form of providing a tension on the glass to preventrattle and breakage thereof, I have provided frame members,

substantially the same as shown in Figs. 1 to 6 inclusive. In this instance, the glass lies next to the frame part 2 and the curtain 1 is interposed between the glass and the upper portion of the angled portion 6 of the frame part 5, as best illustrated in Fig. 10. The curtain 1 is adhesively secured to the angled portion 6* so that the glass 7 may be slid in and out of the frame without wrinkling the curtain.

WVhile I have shown and described preferred embodiments of my invention, it will be understood that changes involving omission, substitution, alteration and reversal of parts, and even changes in the mode of oper ation, may be made without departing from the scope of my invention, which is best defined in the following claims. I
